60% less manual regression for a payments platform

Challenge

A payments platform handling SEPA, SWIFT and FX transfers had no automated tests. Every release waited for a full manual regression, and critical defects in payment flows were found late or by customers.

What we did

We audited the QA process, wrote 600+ test cases for payments, FX and account flows, and automated 305 of them in Playwright and TypeScript. We set up TestOps with reporting and release gates in CI, and added KYC, role and OWASP Top 10 security checks.

Result

Manual regression dropped by 60% and 100+ critical bugs were caught before release. The team now ships with an automated suite that runs on every build.
